Abstract (en)
[origin: WO2019155173A1] The hybrid propulsion is obtained by arranging, around a conventional turbomachine, a reversible electric machine (23) linked to the low-pressure shaft (7) via a mechanical movement transmission (25), a one-way clutch (29) being arranged on the low-pressure shaft (7) between the fan (6) and a low-pressure compressor (1). The low-pressure shaft consists of two aligned portions which can be separated and reconnected. A casing is made up of two portions (40, 41), a first one of said portions of the casing (41) being able to tilt around a horizontal transverse axis of the aircraft relative to a second one (40) of said portions of the casing. One of said portions of the low-pressure shaft, the fan (6) and the reversible electric machine (23) are mounted on the first portion of the casing (41), and the other of said portions of the low-pressure shaft is mounted on the second portion of the casing (40). This device serves to facilitate electric taxiing of the aircraft, using the machine (23) as a motor, whereas the rear of the low-pressure shaft remains stationary. It offers a capacity of efficient electric thrust in flight in the event of engine failure in order to increase the distance between landing points. It may also facilitate vertical takeoff and ascent, or even vertical descent or landing.
